摘要： A method for treating a wash waste liquor, which comprises treating fibers which have been dyed by applying a dye liquor containing a solution or dispersion of a non-ionic dye in a high boiling water-soluble organic medium or a mixture of it with a low boiling medium and then heating the fibers, with a low boiling organic solvent capable of dissolving the high boiling water-soluble organic medium, thereby to wash out the unfixed dye and the high boiling water-soluble organic medium remaining on the surface of the fibers; concentrating the wash waste liquor by evaporating at least a part of the low boiling organic solvent contained in the waste liquor; and extracting the high boiling organic medium from the concentrate using water.
